3D PHOTOGRAMMETRY FOR AURALIZATION -AN APPROACH TO GEOMETRY SIMPLIFICATION AND MATERIAL CATEGORIZAT ION

Proceedings of BauSIM

Abstract

Automated capturing of room models for acoustic simulation might reduce time when acquiring room geometries for acoustic simulations. Additionally, ecologically valid representations of rooms in terms of both modalities, audio and visuals, are required for a qualitative evaluation of sound in architectural contexts. Those requirements might be achieved with the support of photogrammetry techniques. However, traditional ways of acoustic simulation are based on CAD models, thus estimating the original geometries of rooms. In those processes, the time effort and the chances to geometrically differ from the original rooms are not small. For this reason, a new method is presented based on photographies from various camera angles using 3D triangulation techniques. The potentials and applications of this automated method are discussed.
